A Cancer Recognition Method Based on DNA Microarray

The accurate cancer classification is of great importance inclinical treatment. Recently, the DNA microarray technology provides apromising approach to the diagnosis and prognosis of cancer types.However, it has no perfect method for the multiclass classificationproblem. The difficulty lies in the fact that the data are of highdimensionality with small sample size. This paper proposed an automaticclassification method of multiclass cancers based on Biomimetic patternrecognition (BPR). To the public GCM data set, the average correctclassification rate reaches 80% under the condition that the correctrejection rate is 81%.
